WILLIAM VANDERMAN, OF WILLIMANTIG, CONNECTICUT.

LEAD JOINT-RUNNER.

Specification of Letters Patent.

Patented June '7, 1910.

Application filed March 16, 1910. Serial No. 549,720.

To all whom it may concern:

Be it known that I, WILLIAM VANDERMAN, a citizen of the United States,and a resident of Willimantic, in the county of Windham and State ofConnecticut, have invented a new and Improved Lead Joint-Runner, ofwhich the following is a specification.

My invention relates to the class of devices more commonly used byplumbers for packing the joints of piping, such as soil pipes and thelike with molten metal, and the object of the invention is to provide adevice of this class having numerous novel features of advantage andutility.

One form of device embodying my invention and in the use of which theobjects and advantages herein set out may be attained is illustrated inthe accompanying drawings, in which- Figure 1 is a side view of asection of soil pipe showing the manner of use of my improved device.Fig. 2 is a face view on enlarged scale of my improved joint runner.Fig. 3 is an edge view of the same. Fig. 4 is a detail view showing theconstruction of the fastening means.

In the work of laying water, gas or soil pipe or the like, a commonmethod of securing the joint between two sections of pipe is to pourmolten metal as lead into the space between the outer surface of thespigot end of a section and the inner surface of the hub end withinwhich the spigot end of a section is inserted. The diameter of suchpipes difi'er even in the same size of piping owing in some instances todefective casting, but more especially from the fact that pipe ofgreater thickness is required for certain uses than for others. Forinstance, a two inch pipe made for use as a soil pipe will measure lessin diameter than a pipe of the same size constructed for use as a waterpipe, for the reason that the latter is much thicker owing to the higherpressure which it must withstand. In the operation of completing jointsbetween these sections of piping it is essential that the mouth of theopening or space within the hub of the section be then oughly closedexcept for a small opening throdgh which the molten metal is poured, andthat the device shall be so constructed that this gate or opening shallalways be present when the device is used on different sizes of pipe.

The requirements of the device as to hembility necessitates the use ofmaterial which is liable to be more or less affected by the hot moltenmetal, and my improved device is so constructed that the material of therunner is thoroughly shielded at those points where the molten metal ishottest, and I also provide means whereby the gate is always present andthere is no obstruction to the pouring of the metal into the gate, andthe device is also so constructed that it hugs the shoulder of the hubend of a pipe snugly and prevents any outflow of the molten metal.

In the accompanying drawings of an ap proved form of my device thenumeral 7 indicates the body of the runner, which is composed of anysuitable flexible fibrous material. This body is of proper length, andthe ends of each are fitted with shields, consisting preferably of metalcast to shape and each having an end wall 8 to cover the end of the bodypart, a lip 9 extending from the end wall for a considerable distancebackward along the body. The end wall 8 completely covers the end of thebody 7 and a gate is formed by projections from each of these end walls,these projections 10 extending at about right-angles to the body 7 andhaving inturned ends 11 located preferably parallel with the body 7 andlapping past each other, as shown in Fig. 3 of the drawings.

An ear 12 projects upward from one of the lips 9 and at the outer end ofthis car a bolt 13 is pivotally secured, this bolt being adapted to restin a slot 15 in an ear 14 projecting from the opposite lip of theshield.

A thumb nut 16 is secured upon the screwthreaded end of the bolt 13,this nut being of sufficient length to locate the wings 17 at a pointwhere turning action will not be interfered with by the body 7. In orderto lighten the nut and also reduce the amount of engaging screw-threadedparts and thus lessen the friction, the nut has a recess 18 extendingfrom its outer end for a considerable distance inward, as shown in Fig.4.

The ears 12 and 14 being located upon lips secured to the outer edge ofthe body 7 are brought directly in line, so that when the nut 16 istightened to draw the ends of the body part 7 together the force exertedby the nut upon the ears 12 and 14 is in a direct line with the lengthof the body part and parallel with the edgeof the hub 19 of the sectionof pipe a which is being united with the section of the pipe 6. Theconsequence is that the side of the body part is maintained closeagainst the edge of the hub, thus securely closing the mouth.

The ear 14 has a recess 20 immediately underlying the nut 16 withinwhich the end of the latter projects to lock the bolt 18 and preventswinging movement and consequent accidental disengagement from the ear.

I do not limit my invention and the scope of the following claims to theforegoing illustration and description of the preferred form in which ithas been embodied.

I claim- 1. A joint runner including a flexible body part, a shieldsecured to each end of said body part, a gate including two members eachsecured to one of said shields, the outer end of each member being bent,said bent ends both lying in a plane substantially parallel with theside of the body part and lapping one past the other, and means borne bysaid shield for drawing the ends of the body part toward each other.

2. A joint runner including a flexible body part, a shield secured toeach end of said body part, ears rising from each of said shields, abolt pivotally mounted on one of said ears and extending through anopening in the opposite ear, means upon the bolt for drawing the earstogether, and a gate including two members each integrally formed withone of said shields, the outer end of each member being bent and lyingin a straight plane approximately parallel with the bent end of theother part and lapping one past the other.

3. A joint runner including a body part arranged to be bent intocircular form and having a shield completely covering the meeting ends,a sectional gate formed one section integral with each of said shields,ears rising from each of said shields, a bolt pivotally secured to theouter end of one of said ears and engaging an opening in the outer endof the other car, a nut fitted on said bolt and having wings located atthe outer end of the nut, said nut having a recess extending from theouter end inward to a point near its inward end.

t. A joint runner includin a flexible body part, a shield secured to anccovering each end of the body part, each shield having a lip extendingbackwardly along the edge of the body part, ears rising from said lipsin a line substantially parallel with the sides of the body part, a boltpivoted to the outer end of one of said ears and passing into an openingin the outer end of the opposite ear, the latter having a recess in itsface adjacent to said opening, and a nut fitted on said bolt and withits end adapted to rest in said recess whereby accidental disengagementof the bolt from the ear is prevented.

5. A joint runner including a body part arranged to be bent intocircular .form and having a metallic gate member secured to each endthereof, ears rising from each of said metallic members, a boltpivotally secured to the outer end of one of said ears and engaging anopening in the outer end of the other ear, and a nut fitted on said boltand having wings located at the outer end thereof, said nut having arecess extending from the outer end inward to a point near its innerend.
